Answers
Answer:
4% account - $1500
4.75% account - $3000
Step-by-step explanation:
x = amount of money in the account that pays 4% interest
y = amount of money in the account that pays 4.75% interest
x + y = 4500
0.04x + 0.0475y = 202.50
4x + 4y = 18000
4x + 4.75y = 20250
4x + 4y = 18000
- (4x + 4.75y = 20250)
= -0.75y = -2250
y = 3000
x + 3000 = 4500
x = 1500

In the figure, b and c are parallel lines. Which of the following statements are true?
1.Joe claims the measure of angle 3 is equal to 90 degrees.Is he correct?why or why not
2.state the measure of angle 5 and how you know
Thank you!
Answers
Answer:
1. No, Joe is not correct
2. [tex]\angle 5=72^{\circ}[/tex]
Step-by-step explanation:
Given: b and c are parallel lines
To find:
1. whether the given statement is correct or not
2. [tex]\angle 5[/tex]
Solution:
1.
Sum of two angles that form a linear pair is equal to [tex]180^{\circ}[/tex]
[tex]\angle 3+72^{\circ}=180^{\circ}[/tex] (linear pair)
[tex]\angle 3=180^{\circ}-72^{\circ}=108^{\circ}\neq 90^{\circ}[/tex]
So, Joe is not correct
2.
If two lines are parallel then alternate interior angles are equal.
As b and c are parallel lines,
[tex]\angle 5=72^{\circ}[/tex] (alternate interior angles)

Solve: -2 < x + 3 < 5
Answers
Answer:
The answer is
[tex] - 5 < x < 2[/tex]
Step-by-step explanation:
First you have to seperate them :
[tex] - 2 < x + 3[/tex]
[tex]x + 3 < 5[/tex]
Next you can solve it by moving all the unrelated terms to the other side :
[tex] - 2 < x + 3 \\ - 2 - 3 < x + 3 - 3 \\ - 5 < x \\ x > - 5[/tex]
[tex]x + 3 < 5 \\ x + 3 - 3 < 5 - 3 \\ x < 2[/tex]
Answer:
-5 < x < 2
Step-by-step explanation:
Subtract 3 from each of the three sides.
-2 < x + 3 < 5
-2 - 3 < x + 3 - 3 < 5 - 3
-5 < x < 2
What's the eleventh term of a sequence with an explicit rule of ƒ(n) = 2 + 3(n – 1)?
Question 16 options:
A)
ƒ(11) = –31
B)
ƒ(11) = 32
C)
ƒ(11) = 23
D)
ƒ(11) = –22
Answers
Answer:
B. F(11) = 32
Step-by-step explanation:
From the explicit equation,
F(n) = 2 + 3(n - 1)
F(11) = 2 + 3(11 - 1)
F(11) = 2 + 33 - 3
F(11) = 35 - 3
F(11) = 32

what are the solutions of 2x^2 +16+34=0?
Answers
Answer:
5i, and - 5i ⇒ ± 5i
Step-by-step explanation:
We are given the equation 2x^2 + 16 + 34 = 0;
2x^2 + 16 + 34 = 0 ⇒ subtract ( 16 + 34 ) from either side of equation,
2x^2 = - 50 ⇒ divide either side by 2,
x^2 = - 25 ⇒ take square root on either side of equation,
| x | = √ - 25 ⇒ apply imaginary value i,
± 5i, provided absolute value sign | |;
Solution; ± 5i

51-2z-8z=23
We simplify the equation to the form, which is simple to understand
51-2z-8z=23
We move all terms containing z to the left and all other terms to the right.
-2z-8z=+23-51
We simplify left and right side of the equation.
-10z=-28
We divide both sides of the equation by -10 to get z.
